Ubuntu priority
Description
Race condition issues were found in Calibre at devices/linux_mount_helper.c allowing unprivileged users the ability to mount any device to anywhere.
Notes
sbeattie
Ubuntu, from 10.10 (maverick) and after, uses the udisk-based shell script that Martin Pitt wrote instead of the upstream calibre setuid helper. In Ubuntu 10.04 LTS (lucid), the calibre package does not include the setuid helper at all.
